Son of Mothrakk

The Son of Mothrakk is a boss that appears in the same area where you fight Bloodwing in the Wildlife Exploitation Preserve. The boss will spawn when you head back to the area after the storyline has progressed further than this point. The Son of Mothrakk is a reference to the first Borderlands where Mothrakk was a boss. SOM has a chance to drop the legendary the Skullmasher; Bloodwing also shares the same loot drops.
